水污染人工湿地工程治理与安全回灌的研究

水污染是当前急待解决的问题。人工湿地是根据生态学原理实施的一项全新的治理污水处理技术，具有高效率、低投资、低运行费用、低维持技术等优点，尤其适合我国经济发展水平不高、能源短缺、中小城市和广大农村地区应用。目前，基质、植物和微生物的选择和配置是影响人工湿地实施效果的瓶颈和关键所在。利用人工湿地技术处理污染水体，并将净化的水体用于安全回灌，这在很大程度上缓解了我国农业和城市周边的用水紧张问题。

Study on Engineering Governance and Safety Recirculation of Water Pollution Artificial Wetland

Water pollution is the urgent problem waiting to be solved at present. Artificial wetland is a new wastewater treatment technique according to ecology principle, with the advantage of high efficiency, low investment, low circulate expenses, and low maintenance technique and so on. It especially suits for the low development level of economy, energy shortage in our country, and the application in medium small city and large village region. At present, the selection and configuration of substrates, plants and microorganisms become the bottleneck and the key that affect the implementation results of artificial wetland. Utilization of artificial wetland technology to treat pollution water and safety recireulation with the purifying water, to a great extent, will alleviate the problem of water stress in agriculture and peripheral cities of China.
